Big Diamond Heart Necklace 1.56tcw, 14kt Yellow Gold

The Big Diamond Heart Necklace from Treasured & Co. is the largest carat weight in our heart collection — 1.56 carats of natural round-cut diamonds set into a generously scaled heart silhouette in 14kt yellow gold. This is the piece for buyers who want unmistakable presence without crossing into formal-occasion territory.

Stone Details

The pendant features 1.56 total carat weight of natural diamonds. Each stone is round brilliant cut, graded I/J in color and SI1/SI2 in clarity. The I/J color grade is what makes the high carat weight possible at this price point — these are near-colorless stones that face up beautifully in yellow gold (where the warmth of the metal masks any subtle tint), and the SI1/SI2 clarity keeps inclusions invisible to the naked eye.

Setting & Metal

The heart is crafted in 14kt yellow gold (585 purity). Yellow gold is the deliberate choice here: it complements the I/J color grade better than white gold would, and it gives the piece a warmer, more traditional read — closer to vintage heirloom than contemporary statement. The pendant suspends from an 18-inch yellow gold chain.

Why 1.56tcw Matters

Diamond heart pendants under 0.50tcw read as delicate everyday jewelry. Pieces between 0.50–1.00tcw read as confident gifts. Above 1.00tcw, you're in heirloom territory — pieces that get noticed across a room. At 1.56tcw, this necklace is firmly in that last category. It's the right scale for milestone moments: a 25th anniversary, a major birthday, a push present that's meant to be remembered.
